Final answer:

To find the percent of those who like chocolate also like strawberry, we can use conditional probability.

Step-by-step explanation:

To find the percent of those who like chocolate also like strawberry, we can use conditional probability. The formula for conditional probability is:

P(A|B) = P(A AND B) / P(B)

In this case, A represents liking strawberry and B represents liking chocolate. We are given that 70% of friends like chocolate (P(B) = 0.70) and 35% like both chocolate and strawberry (P(A AND B) = 0.35).

Substituting these values into the formula, we have:

P(A|B) = 0.35 / 0.70 = 0.5

So, 50% of those who like chocolate also like strawberry.
